摘要

摘要: 采用2, 6-二氨基吡啶、有机胺、有机酸合成了油基钻井液用固体粉状乳化剂,该乳化剂熔点为120℃,HLB值为1.7,为玻璃态固体,易于粉碎。通过红外光谱对该乳化剂分子结构进行表征,从-CONH₂吸收峰看出,合成过程中发生了酰胺化反应。对乳化剂在不同油水比钻井液中的乳化能力和柴油基、白油基钻井液配制效果进行了性能评价。结果表明,乳化剂的加量为3%时,其在不同油水比钻井液中具有良好的乳液稳定性,当油水比为7:3时,乳液破乳电压大于600 V,乳化率为100%;抗温达180℃,钻井液破乳电压为625 V,提高黏度和切力效果好,动塑比在0.30 Pa/mPa·s以上;热稳定性好,在150℃下连续老化48 h,流变性基本无变化,破乳电压大于700 V,表明该固体粉状乳化剂具有良好的乳化和抗高温性能。

Abstract: A powdered emulsifier used in oil base drilling fluid is synthesized using 2, 6-diaminopyridine, amine and organic acids. It has melting point of 120℃ and HLB value of 1.7. As a vitrescentmaterial this emulsifier is easy to pulverize. Characterization of this emulsifier shows that amidation has taken place in the synthesis process, proved by the presence of -CONH₂ peak in the IR spectrum. At a treatment of 3% in oil base drilling fluids with different oil/water ratios, good emulsion stability is obtained. Oil water emulsion with oil/water ratio of 7:3 has emulsion stability (ES) voltage of 600 V and 100% emulsification. Oil base muds treated with this emulsifier have ES voltage of 625 V, temperature stability of 180℃ and YP/PV ratio of 0.30 Pa/mPa·s. Newly prepared oil base muds treated with this emulsifier has stable properties after aging at 150℃ for 48 hours, and the ES voltage is greater than 700 V, indicating that this emulsifier has good emulsifying capacity and high temperature stability.
